Abstract
The invention provides a high pressure ball valve which comprises a valve body and a wrench, wherein the side faces of the inlet channel and outlet channel of the valve body are respectively provided with a mounting hole, the mounting holes are respectively provided with a connection pipe, a stop valve is arranged between the connection pipes, the wrench of the ball valve and the handle of the stop valve are on the same plane and are in parallel to each other, and the wrench and the handle are connected into a whole through a connecting rod and a pin. The high pressure ball valve has the beneficial effects that the stop valve with a bypass function can balance the medium pressure; and the valve has small open and closure torque, is easy and convenient to operate and has a long serve life.
Description
Technical field
The present invention relates to a kind of ball valve, especially is a kind of high-pressure ball valve.
Background technique
At the high-pressure ball valve that uses in petrochemical industry, nuclear power field, contact the realization initial sealing with the ball seal face at present, realize the self-powering type sealing by pressure medium during work by the spring promotion valve seat that is installed on the valve body.Because pressure medium is big, moment of torsion is big during valve opening, operating difficulties.
Summary of the invention
Pressure medium is big when having now owing to work in order to overcome, and the valve opening moment of torsion is big, the deficiency of operating difficulties, and it is little to the invention provides a kind of unlatching moment of torsion, operates light high-pressure ball valve.
The technical solution adopted for the present invention to solve the technical problems is a kind of high-pressure ball valve, comprise valve body, spanner, have mounting hole at the inlet passage of valve body and the side of outlet passage, connecting pipe is housed respectively on the mounting hole, a stop valve also is housed between connecting pipe.
The spanner of ball valve and the handle of stop valve are positioned at same plane and are parallel to each other, and the two connects as one by connecting rod and pin.
The invention has the beneficial effects as follows bypass action by stop valve, balance media pressure, the valve opening and closing moment of torsion is little, operate light, the valve long service life.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment;
Fig. 2 is the plan view of Fig. 1.
Among the figure: 1. spanner; 2. stop valve; 3. valve body; 4. connecting tube; 5. connecting rod; 6. mounting hole; 7. sell; 8. handle.
Embodiment
As depicted in figs. 1 and 2, a kind of high-pressure ball valve comprises valve body 3, spanner 1, has mounting hole 6 at the inlet passage of valve body 3 and the side of outlet passage, and connecting pipe 4 is housed respectively on the mounting hole 6, and a stop valve 2 also is housed between connecting pipe 4.
The spanner 1 of ball valve is positioned at same plane with the handle 8 of stop valve 2 and is parallel to each other, and the two connects as one by connecting rod 5 and pin 7.When wanting Open valve, rotating spanner 1, by the effect of connecting rod 5 and pin 7, the handle 8 that drives stop valve 2 rotates together, stop valve 2 is opened, the bypass of high-pressure medium by stop valve 2, balance the pressure of ball body of valve both sides, reduced the valve opening moment of torsion greatly, operate light, long service life.
Claims (2)
1. a high-pressure ball valve comprises valve body, spanner, it is characterized in that: the inlet passage of described valve body and the side of outlet passage have mounting hole, and connecting pipe is housed on the mounting hole, and a stop valve also is housed between connecting pipe.
2. high-pressure ball valve according to claim 1 is characterized in that: the handle of described spanner and stop valve is positioned at same plane and is parallel to each other, and the two connects as one by connecting rod and pin.
